BACKGROUND 1. Technical Field

Present invention embodiments relate to communication systems, and more specifically, to managing a conversation or thread of a communication system based on messages or communications varying or drifting from a topic of the conversation or thread.

2. Discussion of the Related Art

Mail clients and online social networks are universal mechanisms to connect people and information in logical and organized manners. These manners enable sharing and processing of information between users. Common mechanisms of sharing and processing information include an inbox, wall, activity stream, timeline, and profile. These mechanisms enable a user to rapidly share information with others and to gather information from others in social and other networks.

For example, a first user and second user may be long time friends and connected on an online social network. The first user may post a message pertaining to getting engaged to be married. A second user may view the posted message and reply with a comment expressing congratulations. A third user may be a casual acquaintance of the first user, and post a message unrelated to the conversation. This may cause other users to feel uncomfortable adding to the conversation.

SUMMARY

According to one embodiment of the present invention, a system processes messages and includes at least one processor. The system receives a message intended for a collection of messages having a common topic. The message is compared to the common topic of the collection of messages to determine relatedness of the message to the collection of messages. The presentation of the message is altered based on the comparing. Embodiments of the present invention further include a method and computer program product for processing messages in substantially the same manner described above.

DETAILED DESCRIPTION

An embodiment of the present invention manages messages or communications that may vary or drift from a common topic of a conversation or thread. A pending message to be posted (to a thread or conversation) is initially detected. Prior messages linked or related to a presentation of the message are analyzed, and the dilution or drift for the pending message from a common topic of the prior messages is determined. The presentation of the pending message or the message contents may be altered. For example, messages which drift from a common topic of the conversation or thread may be hidden, a hashtag or other indicator, such as #hashtag, @mention, etc., may be added, etc.

The message drift may be calculated based on a message view of all other users in the network, and statistically analyzed. A state or age of the conversation and status of the online social network with respect to messages may be examined to determine message drift. Further, a sway of the topic may be leveraged using a visual subject drift in real-time as a subscriber. In this case, topic drift may be illustrated graphically and sufficient changes in the topic drift may be detected and sent to subscribers. In this case, a subscriber may alter presentation of the conversation or thread based on the topic drift.

Present invention embodiments provide several advantages. For example, messages may be managed to avoid topic drift or dilution within conversations or threads. This improves conversations, forums, and question and answer utilities, such as QUORA, TWITTER, IBM CONNECTIONS, STACKOVERFLOW, etc. Further, present invention embodiments may be added to a collaboration or social portfolio, such as those available from FACEBOOK, TWITTER, GOOGLE, etc., to enhance the user experience. Present invention embodiments may remove or otherwise handle messages varying from a topic of a conversation to provide conversations or threads with cohesive messages that collectively are readily comprehendible.

An example environment of an embodiment of the present invention embodiment is illustrated in FIG. 1. Specifically, the environment includes one or more message server systems 110, one or more client or end-user systems 114, and one or more communication server systems 130. Message server systems 110, client systems 114, and communication server systems 130 may be remote from each other and communicate over a network 112. The network 112 may be implemented by any number of any suitable communications media, such as a wide area network (WAN), a local area network (LAN), Internet, Intranet, etc. Alternatively, message server systems 110, client systems 114, and/or communication server systems 130 may be local to each other, and communicate via any appropriate local communication medium, such as a local area network (LAN), hardwire, wireless links, Intranet, etc.

Client systems 114 enable users to interact with communication server systems 130 to send and receive messages or communications. Communication server systems 130 include a communication module 116 and a message control module 120. Communication module 116 provides a platform for communications between users. The platform may include electronic (email) communications, social networks, text messaging, chats, instant messaging, forums, conversation threads, or any other message exchange platform. Message control module 120 detects and intercepts new messages to be posted, and provides those messages to message server systems 110 for analysis.

Message server systems 110 receive and analyze messages to be posted for topic drift. Message server systems 110 include a message variance module 122 to determine topic drift within messages as described below. When sufficient topic drift exists for a message, presentation of the message and/or conversation or thread may be altered.

A database system 118 may store various information for the topic drift determination, such as topic drift or variance scores, access scores, topic drift parameters, thresholds, dictionaries, etc. The database system 118 may be implemented by any conventional or other database or storage unit, may be local to or remote from message server systems 110, client systems 114, and/or communication server systems 130, and may communicate via any appropriate communication medium, such as a local area network (LAN), a wide area network (WAN), Internet, hardwire, wireless link, Intranet, etc.

Client systems 114 may include an interface module 124 that interacts with communication module 116 of communication server systems 130 to interact with the platform. For example, interface module 124 may include a browser to interact with a social network site, forum, conversation thread, or any other message exchange site. By way of further example, interface module 124 may include various applications, such as those for electronic (email) communications, text messaging, chats, instant messaging, or other message exchange mechanisms. The client systems 114, via interface module 124, may present a graphical user or other interface to solicit information from users pertaining to the desired actions, and may provide displays or interfaces presenting the messages. The interface may include a GUI, command line prompts, menu screens, etc.

Message server systems 110, client systems 114, and communication server systems 130 may be implemented by any conventional or other computer systems, such as a laptop, desktop, tablet, smartphone or other mobile computing device, etc. The message server systems 110, client systems 114, and communication server systems 130 are preferably equipped with a display or monitor, a base, optional input devices, and any commercially available and custom software. The base preferably includes at least one hardware processor 115, such as a microprocessor, controller, central processing unit (CPU), etc., one or more memories 135, and internal or external network interfaces or communications devices 125. The communications devices may include a modem, network cards, etc., while the input devices may include a keyboard, mouse, touch screen, or other input device. The software may include server/communications software, communication module 116, message control module 120, message variance module 122, interface module 124, etc., and is provided for execution by at least one hardware processor 115.

The communication module 116, message control module 120, message variance module 122, and interface module 124 may include one or more modules or units to perform the various functions of present invention embodiments described below. These modules may be implemented by any combination of any quantity of software and/or hardware modules or units, and may reside within memory 135 of the message server systems 110, client systems 114, and/or communication server systems 130 for execution by processor 115.

Present invention embodiments detect a new message or comment for a conversation or thread. The new message is analyzed in relation to the conversation or thread. For example, the new message and other conversation messages may be converted to n-grams to determine an amount of overlap between the new message and the conversation. When the new message contains minimal overlap and drifts from a common topic of the conversation, a score is determined indicating a high degree of drift with minimal linkage to prior messages of the conversation. The user providing the new message may be prompted to send a direct message, and the new message may be hidden or deleted from the conversation. Present invention embodiments may be utilized with any social network or messaging system, such as TWITTER, FACEBOOK, IBM CONNECTIONS, JIVE, YAMMER MESSAGING—OUTLOOK, GMAIL, LOTUS NOTES, etc.

A manner of managing a conversation or thread based on variance of a communication or message from a common topic of the conversation or thread according to an embodiment of the present invention is illustrated in FIG. 2. Initially, a user may enter a new message to be posted to a thread or conversation provided by communication module 116 of a communication server system 130. The new message may include an email, comment, reply, or any other type of message, and may be entered from an interface provided by interface module 124 on a client system 114. The entry of the new message may employ a three-phase commit process, such as [DRAFT ANALYZE POST], where each new message traverses these phases. The new message is preferably directed from client system 114 to a communication server system 130 for posting to the conversation or thread.

Message control module 120 of communication server system 130 detects and intercepts the new message at step 205 prior to processing by communication module 116 that maintains the conversation or thread. The message control module 120 provides the new message to message variance module 122 of a message server system 110 to determine drift or variance of the new message from a common topic of the conversation or thread.

The detection and interception of the new message may be accomplished in various manners. For example, the new message may be handled as a push event, where the content of each event or new message is published to a subscriber, and the subscriber acts on the message. In this case, message control module 120 of communication server system 130 may detect the new message and publish the new message to message variance module 122 of message server system 110. The publication may be accomplished by any conventional or custom application programming interfaces (APIs), such as GNIP or COMPLIANCE APIs.

The new message may be handled as a pull event, where content is continuously monitored by the message control module 120 of communication server system 130 for an updated entry added to a message list. For example, HOOTSUITE, TWITTER FEEDS, IBM CONNECTIONS OPENSOCIAL ACTIVITY STREAM each provide a feed that is continually updated. In this case, when a new message is detected, message variance module 122 of message server system 110 is notified by message control module 120 of communication server system 130 and the new message is retrieved by the message variance module 122.

Moreover, a user interface listener may detect a document object model (DOM) event indicating entry of a new message on a user interface provided by interface module 124 on client system 114. Message control module 120 of communication server system 130 may receive notification of the event, and provide the new message to message variance module 122 of message server system 110. Alternatively, message control module 120 of communication server system 130 may notify message variance module 122 of message server system 110 of the event to enable the message variance module 122 to retrieve the new message.

The detection and processing of new messages for drift or variance may be limited to a specific user or group of users, or enabled for all users of a message exchange platform. Further, the detection and processing of new messages may be used with specific messages or communications of a certain length or form. In these cases, various parameters may be utilized defining the desired constraints for the messages. Message control module 120 of communication server system 130 may examine these parameters in response to detecting a new message to determine whether or not the new message is to be provided to message variance module 122 of message server system 110 for processing.

Once the new message is detected and received by the message variance module 122 of message server system 110, each message in the conversation or thread is retrieved at step 210. The message variance module may retrieve these messages from communication server system 130 to determine drift or variance of the new message as described below. Each message is converted into natural language elements, such as n-grams, grammars, lemma forms, etc., and may be augmented with additional context and information to enable the drift or variance to be minimized or normalized for each message (rather than assume each message has drift). Messages with one or a few words may be ignored, and a relationship map between messages may be generated which spans conversations.

Message variance module 122 of message server system 110 determines the variance or drift of the new message at step 215. In particular, a variance score for the new message is determined based on an amount of overlap with the prior messages of the thread or conversation. For example, the n-grams of the new message are compared to the n-grams of each prior message of the conversation or thread. By way of example, the n-grams may include 2-grams, where each message is partitioned into groups of two consecutive words. However, any desired length for an n-gram may be utilized. The n-grams may be compared for exact or partial matches, or for words that are considered related. Relations of words may be stored in a dictionary that may be utilized to provide related words for n-grams for the comparison. The quantity of n-grams in common between the new message and the prior messages may be determined to represent the variance score. The variance score may be compared to a variance threshold to determine that the new message has insufficient variance and is related to the conversation or thread. The variance threshold may indicate a quantity or percentage of the n-grams of the prior messages required to be in common with the new message to be considered related to the conversation or thread.

However, a lack of overlap may alternatively be measured and counted per occurrence. In this case, the variance threshold may indicate a quantity or percentage of the n-grams of the prior messages not in common with the new message to be considered unrelated to the conversation or thread.

Alternatively, the n-grams of the new message may be compared to the n-grams of each individual prior message to determine the variance score for each prior message. The variance scores may be compared to a message variance threshold to determine prior messages with sufficient overlap with the new message. The message variance threshold may indicate a quantity or percentage of the n-grams of the new message required to be in common with a prior message to be related to the prior message. The new message is considered to have sufficient drift or variance to be unrelated to the conversation or thread when an insufficient quantity of prior messages overlap with the new message. This may be determined by comparing the quantity of prior messages with sufficient overlap to the variance threshold. In this case, the variance threshold may indicate a quantity of prior messages required to have sufficient overlap with the new message for the new message to be related to the conversation or thread.

However, a lack of overlap may alternatively be measured and counted per occurrence. In this case, the message variance threshold may indicate a quantity or percentage of the n-grams of the new message not in common with a prior message to be considered unrelated to the prior message. The new message is considered to have sufficient drift or variance to be unrelated to the conversation or thread when a sufficient quantity of prior messages do not overlap with the new message. In this case, the variance threshold may indicate a quantity of prior messages required to have insufficient overlap with the new message for the new message to be unrelated to the conversation or thread.

Sentiment of the new and prior messages may be utilized to determine the variance score for drift or variance of the new message. In this case, sentiment may be determined for the new and prior messages based on various conventional or other natural language processing (NLP) techniques, such as sentiment analysis, affinity analysis, etc. The sentiment may include positive, neutral, and negative sentiment. The combinations of sentiment between the new message and a prior message may each be assigned a sentiment value. For example: a same sentiment for the new message and a prior message may be assigned a first sentiment value, such as a positive value; a different sentiment for the new message and a prior message with one of the sentiments being neutral may be assigned a second sentiment value, such as zero; and a different sentiment for the new message and a prior message, with neither sentiment being neutral, may be assigned a third sentiment value, such as a negative value. The sentiment of the new message is compared to the sentiment of each prior message and the corresponding values from the sentiments are summed to produce the variance score. The variance score may be compared to the variance threshold to determine that the new message has sufficient variance to be unrelated to the conversation or thread. For example, the variance threshold in this case may be zero, where a negative variance score indicating different sentiments may indicate drift or variance of the new message from the conversation or thread. However, the sentiment values may assigned in any manner, and the sentiment values and corresponding variance threshold may be any desired values to indicate relatedness of the new message to the thread or conversation.

The variance scores may be determined for messages across conversations, and the variance scores may be determined from, or based on, the message view of all other users in the message exchange platform. Further, the variance scores may be statistically analyzed by various conventional or other techniques, such as regression or other analysis, clustering, etc., to provide a resulting indication of whether or not a new message is unrelated to a conversation or thread.

In addition, machine learning may be employed to determine whether or not a new message is related to a conversation or thread. In this case, messages, conversations or threads, and/or variance scores may be stored. This information may be used and/or processed against training sets with user provided or known outcomes of relatedness to learn when new massages are related or unrelated to a conversation or thread. The variance scores and thresholds may be adjusted based on the learning to dynamically adapt the determination. Various models may be employed to perform the learning (e.g., neural networks, mathematical/statistical models, classifiers, etc.). For example, a variance score may indicate a new message is related to the conversation. However, for some reasons, the message may still be unrelated to a conversation or thread. These aspects may be learned and employed to adjust variance scores, thresholds, and/or to alter a determination of relatedness of a new message.

When the new message is considered related to the conversation or thread as determined at step 220, the new message is presented in the conversation or thread at step 225. In this case, the determination is provided by message variance module 122 of message server system 110 to message control module 120 of communication server system 130. The message control module 120 enables the communication module 116 to insert the new message into the conversation or thread for presentation by interface module 124 on client system 114. Alternatively, the communication module 116 may provide presentation alterations to interface module 124 to display the new message in the conversation or thread on client system 114.

When the new message is considered unrelated to the conversation or thread as determined at step 220, the presentation of the conversation or thread is altered to accommodate the new message at step 230. In this case, the determination is provided by message variance module 122 of message server system 110 to message control module 120 of communication server system 130. The message control module 120 enables the communication module 116 to alter the presentation of the conversation or thread to accommodate the new message for display by interface module 124 on client system 114. Alternatively, the communication module 116 may provide presentation alterations to interface module 124 to alter and display the conversation or thread on client system 114.

For example, the new message may be hidden from the conversation or thread. This may pertain to hiding messages for a specific group of people, specific users, or for users not engaged in the conversation. In addition, a user sending the new message may be prompted to send the new message as a direct message to the user initiating the conversation or thread.

Further, the new message may be modified. For example, the new message may be used to form one or more separate conversations or threads. The new message may be considered a private message, posted to a specific board, or modified to include an at (@) mention, hashtag, or other indicator the users share in common.

In addition, an access score may be determined for each message added to the conversation or thread subsequent to an initial message initiating the conversation or thread. The access score indicates the relatedness of a corresponding message to the conversation or thread, and may utilize or be derived from the variance score described above. Access control lists are associated with access scores or ranges of access scores, and each access control list indicates users and corresponding access privileges to access the messages with access scores corresponding to the access scores or ranges of access scores associated with that access control list. A high access score indicates a related message, and is preferably associated with an access control list having numerous users indicating the message may be publicly accessible to users. A lower access score indicates an unrelated message, and is preferably associated with an access control list containing limited users indicating the message has lower visibility and may be restricted to select users. The access control lists may be utilized by communication module 116 of communication server system 130 to limit access or visibility of messages to users in accordance with those lists.

The alteration of the presentation may be based on additional criteria, such as the state or age of the conversation, the frequency of messages, and the activity of the user that owns the conversation. Further, a sway of the topic may be leveraged using a visual subject drift in real-time as a subscriber. In this case, topic drift may be illustrated graphically and sufficient changes in the topic drift may be detected and sent to subscribers. In this case, a subscriber, such as message control module 120, may alter presentation of the conversation or thread based on the topic drift.

Operation of an embodiment of the present invention is described with reference to FIGS. 3A-3D. By way of example, a conversation 300 (FIG. 3A) includes a message 305 from a first user (USER 1 as viewed in FIG. 3A) pertaining to getting engaged to be married, and a message or reply 310 from a second user (USER 2 as viewed in FIG. 3A) with a comment expressing congratulations. A new message 315 from a third user (USER 3 as viewed in FIG. 3A) is submitted for posting from client system 114, and includes a comment pertaining to meeting for dinner which is unrelated to the conversation.

Message control module 120 of communication server system 130 detects and intercepts the new message, and enables message variance module 122 of message server system 110 to analyze the message as described above. The message variance module 122 determines that new message 315 is unrelated to conversation 300, and provides an indication of the determination to message control module 120 to alter the presentation of conversation 300 as described above.

Referring to FIG. 3B, conversation 300 may be altered by hiding new message 315 from conversation 300. In this case, conversation 300 includes message 305 from the first user (USER 1 as viewed in FIG. 3B) pertaining to the engagement, and message 310 from the second user (USER 2 as viewed in FIG. 3B) expressing congratulations. In addition, the third user sending the new message 315 may be prompted to send the new message as a direct message to the first user initiating the conversation 300.

Conversation 300 may be altered by creating a new conversation as illustrated in FIG. 3C. In this case, conversation 300 includes message 305 from the first user (USER 1 as viewed in FIG. 3C) pertaining to the engagement, and message 310 from the second user (USER 2 as viewed in FIG. 3C) expressing congratulations. A new conversation 320 is created between the first user and the third user. Conversation 320 includes message 315 from the third user pertaining to meeting for dinner, and may further include message 305 from the first user pertaining to the engagement. Message 315 may be a direct message to the first user.

Referring to FIG. 3D, an access score is determined for each message subsequent to the initial message 305 in conversation 300 to limit access to the messages. In this case, conversation 300 includes message 305 from the first user (USER 1 as viewed in FIG. 3D) pertaining to the engagement, message 310 from the second user (USER 2 as viewed in FIG. 3C) expressing congratulations, and message 315 from the third user (USER 3 as viewed in FIG. 3D) including a comment pertaining to meeting for dinner. Message 310 and 315 each have an access score 325, 330 indicating relatedness of the message to the conversation. The access score may utilize or be derived from the variance score as described above. Access control lists are associated with access scores to limit access to the particular message. By way of example, message 310 has an access score 325 with a value of 100 indicating message 310 is related to conversation 300. The access control list associated with this score contains numerous users, thereby enabling access on a large or public scale. By way of further example, message 315 has an access score 330 with a value of 25 indicating message 315 is unrelated to conversation 300. The access control list associated with this score contains limited users, thereby restricting access to select users. The access scores or other indicators may be presented in the conversation to indicate any access restrictions.

It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
